ATalker is a Web-based text-to-speech utility, based on the Festival Text-to-Speech system. With synthesized speech ATalker can read text out loud over the Web. With the ATalker Theme installed, the ATutor interface and feedback messages can be read out loud. See the demo to try ATalker yourself, the ATalker Readme for documentation, and the ATalker download to get a copy for your ATutor installation.

The current version of ATalker (version 0.1, the first version) was developed on a Linux based system, but should, in theory, work on other systems that support Festival and PHP. This version is experimental, available primarily for testing and community comments. Post your comments, suggestions, bug reports, kudos, etc., to the NEW! ATutor Add-ons Forum

ATalker can currently produce English and Spanish voices. The potential for many other languages is available through the Mbrola Project for those who would like to contribute. This version of ATalker is based on the Festival 1.4.3 Speech Synthesis System, though should function properly with Festival 2.0.
